Abstract: ABSTRACT OF THE DISCLOSURE     A portable machine tool, comprising a base structure, a work surface supported by the base structure for supporting, in use, a workpiece, and a column pivotally connected to the base structure and being pivotal be-tween an upstanding operative position in which the column extends upwardly above the work surface and a lateral inoperative position.  An operating unit is attached to the column and is supported thereby above the work surface in the operative upstanding position for operating, in use, on the workpiece.  A locking arrangement releasably secures the column in the operat-ive upstanding position.  Preferably the column is pivoted behind and to the rear of the base structure, and a part of the work surface is removable to expose a space inside the base structure in which the operating unit is at least partially housed when the column is pivoted to the inoperative lateral position.  In this way the machine tool, which is preferably a radial arm saw, is made more compact for transporting and/or storage.

Abstract: ABSTRACT OF THE DISCLOSURE      A rear illuminated device for displaying prices of articles is of the type that includes a housing, a light source in the rear of the housing, a front frame mounted on the housing which has a plurality of horizontal rows of windows, each of said windows being adapted to display one rear illuminated numeral of the price of an article, film strip carrier means mounted in the housing, there being a film strip carrier in closely spaced cooperating rela-tionship with each window, and each said carrier cooperating with the front frame to define a guide slot in which a section of a film strip is held effectively flat in the window, and a film strip supported on each carrier for endwise movement through a guide slot, each section of a film strip being adapted to display one of the numerals from 1 through 0 in the window.  Each film strip is a continuous loop which loosely encircles the film strip carrier and is positioned entirely forward of the light source in the housing, and adjacent film strip loops are in side abutting relationship so as to be mutually confining.  Each film strip carrier has a transverse slot centered between the lateral sides of a window immediately adjacent and parallel to a transverse margin of the window, and indexing holes in each film strip are aligned with a slot and so associated with the film strip sections that when a hole is moved from one end of a slot to the other it moves the film strip by one section and centers a section in the window.

Abstract: RIM ASSEMBLY Abstract of the Disclosure A multi-piece rim assembly (50) comprises a rim base (51), sealing member (52), lock ring (53) and bead seat band.  The sealing member (52) and lock ring (53) have specified positions such that each is at least partially disposed in an annular groove (57,58)in the radially outer surface of the rim base, with the lock ring being nearer to an axial end (55) of the rim base than the sealing member.  The bead seat band is coaxial with and slidably mounted around the rim base.  When all of the components of the rim assembly are in their specified positions, the bead seat band engages the sealing member to form an airtight seal.  If the entire lock ring is not in its specified position, an axial end of the bead seat band contacts the lock ring and prevents the airtight seal from being formed.

Abstract: ABSTRACT OF THE DISCLOSURE          Polymerization slurries of elastomeric isoolefin homopolymers and copolymers, such as butyl rubber, in dilu-ents such as methyl chloride are effectively stabilized against agglomeration of polymer particles through addi-tion of minor proportions of an hydrogenated preformed copolymer stabilizer having both a lyophobic and a lyo-philic portion.  The chemical and structural nature of the lyophobic and lyophilic portions which comprise the co-polymer stabilizer are significant in determining the ex-tent and method of hydrogenation for production of the most effective stabilizer.  Agglomeration of polymer prod-ucts is effectively prevented, yielding a number of signi-ficant processing advantages.  The process is especially adaptable to the production of isobutylene-isoprene butyl rubber.

Abstract: TRIM PRESS WITH OSCILLATING    CANOPY SHEET FEED      ABSTRACT OF THE INVENTION         An oscillating canopy is employed in the feeding of an elongate sheet of synthetic plastic material having articles, such as cups, for example, formed in the sheet, to a die which trims the articles from the sheet.  The canopy has a downwardly concave curved upper portion upon which the sheet is supported by a series of rollers.  The canopy is driven in forward and return strokes in pivotal movement about an axis located at a radial distance from the curved upper portion which is a greater distance from the discharge end of the curved upper portion than from the sheet receiving end so that tension is maintained on the sheet during the feeding stroke.  The sheet-supporting rollers are mounted for rotation in one direction only, this direction being that in which the rollers can roll relative to the sheet on the return stroke of the canopy.

The yield is increased by up to 50% by this method. The process is of particular application to the preparation of febarbamate, 1-(3-nbutoxy-2-carbamoyloxypropyl)-5-ethyl-5-phenyl-(1H,3H,5H)pyrimidlne-2,4,6-trione. Also described is a method of treating geriatrics using febarbamate which has particular advantages in reducing irritability and antisocial behaviour.

Abstract: ABSTRACT           A metal or metal compound coating is formed on a face of a hot ribbon of freshly formed glass as it travels forwardly through a coating station where coat-ing precursor material is sprayed onto the surface of the glass.  The coating precursor material is sprayed in one or more streams of droplets which is or are directed downwardly and forwardly towards the ribbon and is repeatedly displaced to and fro across the ribbon path so that the ribbon is scanned by the droplet stream(s).  Especially in order to form a thick coating of tin oxide on a rapidly moving ribbon, the velocities of the droplets in the stream(s) are such that sub-stantial splashing occurs at the ribbon face.  Gas is continuously discharged along axes behind the droplet stream so as to maintain a forwardly directed flow of gas which envelops the rear half of the or each stream at least at the bottom portion of the stream trajectory and sweeps past the sides of such stream with sufficient velocity to entrain substantially all the splashes away from the stream.  The entrained material is then removed from the environment of the ribbon through exhaust ducting.

Abstract: Abstract A speed sensitive, load sensitive and AC line voltage fluctuation insensitive, motor starting system is provided for an AC motor having a main winding and an auxiliary winding     both connectable across an AC power source    .  Relative magnitudes of main and auxiliary winding voltages are sensed and compared. The auxiliary winding is disconnected     from the AC source when the auxiliary winding voltage, including the components from the AC source and from rotationally induced voltage, rises above a predetermined value relative to the main winding voltage as a function of motor speed.  After starting, when the motor is in a run mode and the auxiliary winding is disconnected from the AC source, only the rotationally induced auxiliary winding voltage is sensed.  The auxiliary winding is reconnected to the AC source when the rotationally induced auxiliary winding voltage decreases below a given value relative to the main winding voltage cor-responding to a given stall condition, to automatically restart the motor.
